Hall A Update

Thia Keppel

6/4/13


Near term accelerator schedule same as last meeting

Near term accelerator schedule – same as last meeting

  • Accelerator Run II: Beam in hall 3/2014, or maybe as early as 1/2014 (?)

    • > 1.1 GeV/pass, 3 pass spin-up to Hall A

    • up to 5.5 pass to D by ~5/14

    • Shut down 5/3/14

  • Accelerator Run III: 8/30/14 – 12/1/14

    • CD4A milestones

      • 12 GeV 5.5 pass capable installed

      • 11 GeV 5 pass to A, B, C installed

      • > 2 nA 2.2 GeV single pass transported

    • Plan

      • E > 2 GeV/pass, 10 GeV to Hall D

      • 2 Hall operation

  • Accelerator Run IV: 2/13/15 – 6/1/15

    • E > 2 GeV/pass, 2 hall operation

    • CD4B Halls B,C,D operational, > 6, 6, 10 GeV

      • Schedule rebaseline likely – won’t effect Hall A or accelerator

  • Physics Run I: 8/30/15 – 12/23/15

    • E > 2 GeV/pass

  • Physics Run II: 2/6/16 – 6/25/16

  • Physics Run III: 9/12/16 – 12/22/16

  • Spring, fall, spring, fall runs continue….

Rebaselining might carry some changes, but unlikely to effect SBS

General hall near term thoughts for sbs

General Hall near term thoughts for SBS

  • Hall A should see first beam in less than ~1 year 

    • Upgrade and infrastructure work underway

      • Beamline– energy, current, position, polarimetry,…

      • HRS’s – detector upgrades and general refurbishing

      • Many things to do and help appreciated!

  • Experiments using ~standard equipment scheduled initially

    • Allows for parallel efforts preparing for new equipment (3He target, PREX, SBS,….MOLLER,….)


Sbs current activities

SBS Current Activities

  • Hall A currently supporting “pre-R&D” and SBS-related work

    • 3He target development (Gordon Cates)

    • GEM tracker prototyping at UVA (NilangaLiyanage)

    • Hadron calorimeter (Gregg Franklin) Fermilabscintillator purchase approved

  • 10/1/12 SBS “Program” started with DOE

    • Subset of the proposed physics program (magnet and GEMs)


Sbs design and engineering see robin s talk

SBS Design and Engineering (See Robin’s talk!)

GEn

  • Yoke modification drawings ~30% complete

  • Design work ongoing for magnet counter weight support, will incorporate movement of support to relocate magnet

  • Design details of rollers, jack mounts, magnet bracket, floor plates ongoing, ~65% complete

  • Detailed drawings of new coils ~25%

  • Power supply specification completed, in procurement

  • Layout and design of shielded beampipe and vacuum snout~20%

  • Defining field clamps and design of clamp supports ~15%

  • Detector support design ~20%

  • Mid-June delivery expected for magnet from BNL

GMn


Other thoughts

Other Thoughts

  • New PAC procedures for no-additional-beamtime-needed requests

    • Does the SBS collaboration anticipate experiments like this?

    • If so, suggest working on a process for review

Looks on track for first SBS run in 2016 or 2017!
